Description
The present invention relates to a kind of valve module, more specifically relate to a kind of valve module for continuous cyclic drilling.
Well boring is performed by the rotation of the drill bit being positioned at drill string base portion.Drill string is formed primarily of being threaded connection each union be bonded to each other at every end place.
Bit penetrates subsurface formations and the final key function arriving the expectation target degree of depth.In order to make bit, usually utilize turntable or top drive to provide moment of torsion to drill string, drill string will cause bit below.Bit can also be realized by downhole motor independent of drill string rotating, and this downhole motor provides energy by the flowing along the downward drilling fluid of drill string.
In arbitrary rotation approach, drilling fluid is all finally downward along drill string, through drill bit and by bore hole annulus to cocycle.This flowing of drilling fluid is used to provide that sufficient bottom outlet is clean, chip conveying and drill bit cooling.Drilling fluid is also supposed to by producing enough pressure in annular space and provides hole stability, flows into prevent the accident of formation fluid and prevents borehole collapse.Drilling fluid can represent the various mixtures be made up of oil, synthesis or water-based fluid (it contains solid-state content and aerated liquid, foam, mist and the inert gas of different amount).
Need sizable amount of pressure the bottom outlet of aspiration level cleans successfully to provide to make drilling fluid, chip conveying and the speed needed for borehole pressure circulates along path described above.As a result, usually configuration positive-displacement pump utilizes and passes downwardly through vertical tube manifold injection drilling fluid as the top drive of one section of flow duct or kelly bar (kelly) along the top of drill string.Positive-displacement pump is commonly referred to as slush pump, and provides and make fluid move necessary mechanical force by whole well system.
Along with the increase of drilling depth, additional pipeline section must be added into drill string top, to allow drill bit to move on towards expectation target.Alternatively, when drill bit is pulled out from hole, pipeline section must be removed from drill string.Traditionally, increasing the process of drilling pipe is all by stopping drilling fluid circulation, being disconnected by top drive, increase by one section of pipe from drill string, and top top drive being connected to again drill string also starts that the circulation of drilling fluid carries out again.
During process described above, stop fluid circulate and bring challenge to drilling well, these challenges can solve by wherein not stopping the continuous circulation system circulating.In this one is proposed, the flowing of drilling fluid is moved away completely from top drive and is guided to the side ports in drill string.Side ports provides the alternative flow path leading to drill string main aperture.When doing like this, be closed at drill string top and top drive port so that when increasing another section of pipe, circulation can continue through side ports without interruption.This flowing transfer can be carried out by the one way valve being arranged in side ports, and this one way valve has the connector for flexible pipe, and this flexible pipe receives flow of pressurized fluid via standpipe manifold from drilling platform slush pump.Once top drive is connected again, then drilling fluid flowing can also be shifted completely by the top of drill string.
At United States Patent (USP) 8,210, in an embodiment of this system disclosed in 266B2, in the valve chest of general cylindrical, install poppet check valve, valve chest is arranged in the side ports (as shown in Fig. 5 a, Fig. 5 b, Fig. 5 c, Fig. 5 d, Fig. 6 a, Fig. 6 b, Fig. 6 c and Fig. 6 d) of drill string wall.Side ports is perpendicular to the main aperture direction of drill string.Cylinder valve housing is in position by being threadedly engaged with the side ports of drill string.Cylinder valve housing can also utilize and extend to stop pin in drill string body through the aperture in housing and in position.These stop pins prevent valve chest from withdrawing.Also other appropriate device any or bolt of valve chest being fastened to side ports can be used.Valve chest also comprises the medium pore parallel with the side opening holding poppet check valve.Utilize O type ring between cylinder valve housing drill string body, produce the sealing of fluid-tight.
Poppet-type valve member is included in the valve rod that one end is mounted to cylindrical disc in a vertical manner.Circular valve seat is positioned at the outside of cylinder valve housing.When situated in the closed position, valve rod reaches in the hole of valve chest, and simultaneously slightly wider than housing bore diameter cylindrical disc is seated on valve seat.In closed valve position, between valve seat and cylindrical disc, form metal/metal sealing.The sealing of this metal/metal is used as the anti-fluid when continuous circulation system disconnects and flows out from drill string during drilling well period and the main barrier flowed back to by valve chest.In addition, the valve module promoting type is rinsed the advantage being positioned in side opening and having and do not hinder and flowed by drill string main aperture completely.
In order to be radially positioned in the hole of valve chest by valve member, arrange annular flange flange, this annular flange flange extends in the central aperture slightly wider than the diameter of valve rod from the valve chest with metal spoke.Valve rod extends through this central aperture.Valve is by spring-biased in fastening position, and this spring is being arranged on outwards towards the extension of valve rod free end between the circular groove in annular flange flange, and wherein this valve rod designs fastening by channel nut or other mechanical nut.In order to lift valve is pushed to open position, must spring force be overcome, thus cylindrical disc be raised up from circular valve seat.When doing like this, fluid by the hole of valve chest, around the spoke in collar flange, and can be flow in the main aperture of drill string by the space between dish and valve seat.This power can be disposed by flexible pipe by means of the flow of pressurized fluid from slush pump, and this flexible pipe can be connected to from standpipe flow manifold the valve chest being arranged in drill string side ports.
When valve is not by side ports transmitting fluid, the hole of cylinder valve housing can utilize the hard hat assembly providing secondary seal to protect.In an embodiment of the invention, this cap is by a pair of component type Structure composing.Outer cap slides in the hole of valve chest, until the lip configuration bonding station in bayonet connection and cylindrical housings, thus by components in position.Interior cap is threadably engaged the inside being fastened to outer cap.Interior cap forms secondary seal via the inner surface of O type ring and valve chest.This secondary seal provided additional barrier when valve seat and cylindrical disc lose efficacy, to provide enough metal/metal sealings.Coupling assembling is used to install and remove this cap.
This invention can use in combination with another valve at the top of fixing drilling pipe main aperture.
In US Patent No. 7,252,151, US7,322,418, US6,412,554 and US6,119, other embodiment of continuous circulation system is disclosed in 772, but these features are mechanical-hydraulic systems of the high complexity containing multiple plunger (ram), these plungers are expensive, relate to somewhat complex design and maintenance, and take extensive work space on offshore boring island floor.Equipment fair in U.S. Patent application 2011/0308860 does not provide the chance of the metal parts of the frequent wear changed in valve opening.In addition, valve member is positioned in the main flow path of drill string by this equipment, and result makes valve stand strong corrosion.United States Patent (USP) 8,016,033B2 it is also proposed a kind of circulating system based on side ports, and this system comprises the valve of the direct flow diameter of the main aperture being arranged in drill string, thus this system also stands strong corrosion.Finally, United States Patent (USP) 2,158,356 provide a kind of side ports circulating system with flapper valve.Use the high pressure sealing that flapper valve does not traditionally provide solid.
The working of an invention mode described in United States Patent (USP) 8,210,266B2 above solves the many shortcomings run in current continuous circulation system.Firsts and seconds sealing barrier sealing mechanism provides the increase guarantee can not being fled from drill string by the flow of pressurized fluid of drill string main aperture via side ports.Whether effectively and protect crew hard hat allows the release of any trapping pressure to carry out indicating sealing.When primary barrier lost efficacy, the locking system on hard hat can not allow cap to discharge.This design also by the stop pin being threadedly engaged or clamping drill string body between the external surface of valve chest and the inner surface of side ports wall and O type ring and pressure tight seal valve module is fixed to side ports.Lift valve provides the sealing firmer than flapper valve.In addition, this design can not hinder the flow path in the main aperture of drill string.Finally, use plunger and ring-type retainer to carry out the high complexity of continuous circulation process and expensive facility compared to configuration, use the continuous circulation valve proposed more simply too much.

By this layout, nut 29 can be locked in the variable position on valve rod 20a, by the unblock of the biasing force restriction nut 29 of spring 26.
Although not essential, this embodiment of the present invention is also provided with cap 30, and this cap 30 is provided with the top 30a of substantial circular, and the general cylindrical wall 30b that diameter is less than this top 30a extends from this top 30a.Wall 30b extends in the main channel of valve body 12.
In use, cap 30 is fixed to valve body 12 by the buckle connecting structure 32 be arranged on the external surface of the wall 30b of cap 30.In this embodiment, be provided with four this buckle connecting structures 32, these four buckle connecting structures 32 are roughly evenly spaced apart around the wall 30b of cap 30, and the space between adjacent buckle connecting structure 32 occupies the only about half of of the excircle of wall 30b altogether.Buckle connecting structure 32 all engages with the corresponding lip configuration 34 extended to from valve body 12 in main channel.Like this, in this embodiment, be provided with four lip configuration 34, and these four lip configuration 34 are spaced apart around the even circumferential ground of the inner surface of valve body 12, altogether occupy the circumference being less than half.
Valve module 10 can also be provided with one or more locking projection, and these projections extend up to main channel diagonally from the downside of lip configuration 34.In this case, for each locking projection, be provided with the corresponding recess of the end even as big as holding locking projection in the central authorities of the buckle connecting structure 32 of cap 30.
Thus, like that cap 30 can be fixed to valve body 12 according to following.Cap 30 is oriented so that one of gap between each buckle connecting structure 32 with adjacent lip configuration 34 is aimed at.Cap 30 is inserted in the main channel of valve body 12, until top 30a is slightly lower than the first end 12a of valve body 12, and then cap 30 is rotated about 45 °, until each bayonet socket syndeton 32 engages with in lip configuration 34.When arranging locking projection, subsequently each locking projection is positioned in the corresponding recess be arranged in buckle connecting structure 34.Thus buckle connecting structure 32 prevents cap 30 from returning from valve body 12 with the joint of the lip configuration 34 of valve body 12, and the location in the recess of locking projection in buckle connecting structure 32 ensure that cap 30 is correctly aimed at relative to valve body 12, to realize the Maximum Contact between buckle connecting structure 32 and lip configuration 34, and cap 30 is stoped to rotate relative to valve body and depart from aligning.
In order to contribute to realizing making buckle connecting structure 32 engage required rotation with lip configuration 34, the top 30a of cap 30 is provided with multiple aperture 36, special tool can be inserted in these apertures 36.Thus can rotate turncap 30 by instrument.In this embodiment, be provided with eight such apertures 36, thus instrument is provided with eight corresponding pins.Determine to help user when cap 30 is correctly aimed at relative to valve body 12, the external surface of lip configuration 34 is provided with corresponding aperture 38, and when cap 30 is correct on time, the aperture 38 of these correspondences arranges with the aperture 36 in cap 30.Thus, when cap 30 relative to valve body 12 correctly on time, the pin of instrument can insert in the aperture 38 in lip configuration 34.When instrument is suddenly mobile towards valve body 12, user will feel this point, and thus again can guarantee that the aligning of cap 30 is correct, and without the need to further rotating.
Alternatively, one or more in buckle connecting structure 32 can be provided with anti-rotational feature, thus cap 30 can only rotate a certain amount of (such as 45 degree) before the hard retainer of arrival.This can comprise chocking construction, and this chocking construction extends from the outside 31a of cap 30 and aims at an end face of buckle connecting structure 32 between buckle connecting structure 32 and the top 30a of cap 32.Therefore, when cap 30 have rotated make buckle connecting structure 32 to aim at completely with lip configuration 34 needed for amount time, the edge join of in anti-rotational feature and lip configuration 34, therefore prevents cap 30 from further rotating.
In this embodiment, buckle connecting structure 32 becomes about miter angle with the matching surface of lip configuration 34 relative to the longitudinal axis of the main channel in valve body 12, and the radially-inwardly part of these matching surfaces is closest to the first end 12a of valve body 12.
Although the structure that cap 30 can be integrated, but in this embodiment, this cap 30 is formed into two parts, that is: exterior part 31a and inner part 31b, this exterior part 31a provides the part comprising buckle connecting structure 32 of the periphery of top 30a and wall 30b, this inner part 31b provides the middle body of top 30a and the bottom of wall 30b, and this bottom has circumferential recess, and potted component (being O shape ring 40 in this embodiment) is positioned at this circumferential recess.Exterior part 31a and inner part 31b tightens together by means of the joint of the screw thread arranged around the outside of inner part 31b and the inside of exterior part 31a.
Be arranged in the exterior part 31a of cap 30 to make buckle connecting structure 32 and lip configuration 40 lock the aperture 36 engaged for turncap 30.Therefore, arranging this two component type structures is advantageously, because during exterior part 31a carries out this rotation, the joint of the screw thread of exterior part 31a and inner part 31b causes exterior part 31a slightly to move towards the first end 12a of valve body 12, thus make buckle connecting structure 32 closely engage with lip configuration 34, and prevent cap 30 from valve body 12, carrying out any substantial motion.
But, should be realized that, other fastener can be used to be remained in valve body 12 by cap 30.Such as, the quick connecting method adopting screw thread or other type any can be changed into.
In this embodiment, the diameter due to the top 30a of cap 30 is less than the internal diameter of the first end 12a of valve body 12, and therefore the top 30a of cap 30 can insert in the main channel of valve body 12 at the second end 12b place of valve body 12.But the internal diameter of the Part II 14b of valve seat 14 is less than the external diameter of the wall 30b of cap 30.Thus, the Part II 14b of valve seat 14 as preventing cap 30 to be pushed completely by the retainer of main channel.
When cap 30 is correctly positioned in valve body 12, buckle connecting structure 32 is between lip configuration 34 and the Part II 14b of valve seat 14, and O shape ring 40 engages with the Part II 14b of valve seat 14 sealing providing basic fluid-tight.Which ensure that cap 30 provides anti-fluid to flow through the secondary seal of the main channel of valve body 12 when the seal failure provided by valve member 30.
Therefore, valve seat has the second valve seat, and in this embodiment of the present invention, this second valve seat is also ring-type, and becomes the angle of 30 ° to 60 ° relative to the longitudinal axis of the main channel in valve body 12.
Should be realized that, the angle of orientation of the first valve seat and the second valve seat is not vital.Any one or the two can be generally perpendicular to the longitudinal axis (but structurally this is inadequate) of the main channel in valve body 12, or can with the angle orientation of the longitudinal axis close to the main channel in parallel valve body 12 (but in this case, be there is marked change by slightly changing of valve-seat diameter in position when making valve member or cap engage with valve seat).Applicant has been found that the angle of about 60 ° provides the reasonable tradeoff between the consideration of these contradiction, because which provide good fluid flow characteristics, and has less corrosion than having more low-angle form to sealing surface.Can by using higher manufacturing tolerance to alleviate with the variation issue of the valve member/cap position of this steep angular dependence (-dance), and for the first valve seat, steep angle allows the dish of valve thinner a little, and this is because the flexural stress on dish is less, and compressive stress is larger.
As shown in Figure 3, in use, valve module 10 is arranged in the part being arranged on drilling pipe 42 or for inserting in the side ports 46 in the joint in drilling pipe.Drilling pipe 42 has the main channel 44 being in substantially parallel relationship to its longitudinal axis A and extending, and side ports 46 extends through drilling pipe (in this embodiment, being generally perpendicular to its longitudinal axis), is thus connected the outside of main channel 14 with drilling pipe 42.Valve module 10 is positioned at drilling pipe 42, wherein the second end 12b of valve body 12 flushes substantially with the external surface of drilling pipe 42, and valve seat 14 and valve member 20 are at least mainly positioned at side ports 46, thus valve module 10 limit fluid can not flow along the main channel 44 of drilling pipe 42 on any significance degree.
In this embodiment, around the screw thread in the wall of side ports 46, valve module 10 is fixed to drilling pipe 42 by means of what be arranged on the external surface of valve body 12 and drilling pipe 42.
The face around side ports 46 of drilling pipe 24 is provided with the step or shoulder 48 that extend radially inwardly, and step or shoulder 48 are provided for the placement surface of valve module 10, and in this embodiment, the longitudinal axis B that this placement surface is generally perpendicular to side ports 46 extends.Shoulder 48 (it has the diameter that the external diameter being less than valve body 12 and valve seat 14 is still greater than the diameter of the dish 20b of valve member 20) between the outside 46a (it has the diameter of the external diameter being greater than valve body 12 and valve seat 14) and the inside 46b of side ports 46 of side ports 46 extends.Therefore, valve module 10 is inserted in side ports 46 from the outside of drilling pipe 42, is placed on shoulder 48 until valve seat 14 becomes.
Thus, the Part II 14b of valve seat 14 is trapped between valve body 12 and shoulder 48, and therefore the location of valve seat 14 between valve body and shoulder 48 is as the mechanism reliably remained on by valve seat 14 in valve module 10.And, by the screw thread between fastening valve body 12 and drilling pipe 42, enough compressive forcees can be applied to valve seat 14, to produce the sealing of basic fluid-tight between valve module 10 and drilling pipe 42.In this embodiment, the sealing of this basic fluid-tight is provided with the joint of shoulder 48 by the potted component of facility on valve seat 14 and O type ring 18.Thus, substantially prevent the outside of valve module 10 and drilling pipe 42 around side ports 46 face between fluid flowing.
In alternative embodiment of the present invention, valve body 12 can be provided with multiple (such as four) lock stud, and each stud is through threaded bores, and described threaded bores passes radially outward therethrough valve body 12 from main channel and extends to the outside of valve body 12.In this case, each lock stud has screw thread, and the inner is provided with the head with the hex pockets that can engage with Allen key.In order to valve module 10 is fixed to drilling pipe 42, when lock stud is retracted by valve body 12 inserting side port 46, thus them are made not extend beyond the external surface of valve body 12.Then rotary valve 12 in side ports 42, to guarantee that lock stud is aimed at the corresponding aperture in the wall being arranged on side ports, and is screwed to stud in the aperture in drilling pipe 42 with the engagement of each stud successively by Allen key.Therefore prevent and from side ports, valve module 10 is removed.But, will recognize, except being threaded, also this lock stud can be set.To recognize, bolt or other suitable fastener any can be used.
In the general operation mode process of drilling pipe, in the main channel 44 of drilling pipe 42, there is the pressure of Forced Valve assembly 20 against valve seat 16.In order to use side ports 42, cap 30 is removed.Once cap 30 is removed, the lip configuration 34 of the adapter (not shown) with valve body 32 that are provided with corresponding buckle connecting structure can be engaged.This adapter is provided with suitable seal, thus will there is the sealing of basic fluid-tight between valve module 10 and this adapter.The seal can be the O type ring similar with the O type ring 40 on cap 30 or piston seal, and the seal and the second valve seat are adjacent on the parallel circle cylindroid of the Part I 14a being sealed in valve seat 14.Thus fluid pressure can be fed in the main channel of valve module by this adapter, and once the amount of internal pressure that institute's applied pressure exceedes in the main channel of drilling pipe 42 is enough to overcome the biasing force of spring 26, is then mentioned starting from valve seat 16 by dish 20b.Now, valve module is positioned at open position, and fluid flows into by side ports 42 in the main channel 44 of drilling pipe 42.
Once flowing stops, and pressure drop in adapter is to lower than the pressure in drilling pipe 20, then valve 20 will cut out.Valve when guaranteeing at the central applied pressure do not had from drilling pipe 42 always and do not have outside applied pressure is always maintained in its closed position by spring 26.
If the fluid pressure in adapter is relative to the fluid pressure balance in drilling pipe 42, then will recognize, fluid pressure in adapter possibly cannot be enough to valve member 20 to move to open position, in this case, adapter can be provided with mechanical actuator and valve member 20 is pushed to open position from valve seat 16.This mechanical actuator automatically can carry out this action when adapter is fixed to drilling pipe, or needs to carry out manual operation to this actuator.
To recognize, when opening when valve module 10 and have rapid fluid to flow along side ports 46, this high-velocity fluid fails to be convened for lack of a quorum to valve seat 14, and particularly valve seat 16 and radial spoke 22 bring significantly erosion and corrosion.This erosion/corrosion is undesirable especially, provides and the ability of the effective sealing of valve member 20, spoke 22 sutaining valve component 20 ability making valve member 20 placed in the middle because it can damage valve seat 16.
By making valve seat 14 and valve body 12 become two individual components, valve seat 14 can be replaced by during excessive erosion/corrosion, and without the need to also changing whole valve body 12.By only needing to change and transporting valve seat 14, remarkable cost savings can be realized, simplify logistics maintenance and material nonrecurring cost.
Two component types design also allow for valve module 10 be exposed to high-velocity fluid stream and be the most easily subject to this high-velocity fluid stream corrode and corrosion parts carry out optimal material selection, make to resistance to wear and corrode maximization.When valve body and valve seat are formed by single parts as in the state of the art, be difficult to select single stainless steel grade to realize the correct balance of ductility for these parts and hot strength.Like this, when valve module is formed as in the state of the art, valve chest is typically made up of high strength steel, and carries out chemical treatment to improve its corrosion resistance to this steel.Such as, this process can be wherein apply the liquid phase nitrogen treatment of black oxide layer as protective coating.And, because the metal/metal sealing between valve seat and valve member is subject to remarkable corrosion due to the high speed pressurized drilling fluid through valve module, in use therefore by utilizing hardened surface material to give sealing surface secondary coating.Such as, high-velocity oxy-fuel can be utilized to apply thin hard metal/ceramic layer.Although this process can increase corrosion resistance and corrosion resistance, this processing procedure occupies manufacturing time and the cost of considerable part.In addition, under the abrasive action produced due to pressurized drilling fluid flowing, this coating may be etched, and this erosion actually increases the risk of corrosion.
Two component types designs of the present invention allow optimal selections to be more suitable for the material of their functions in valve module 10.Such as, still the high strength steel with the ductility specification that API 7-1 requires can be disposed for valve body 10, valve member 20 and hard hat assembly 30.Like this, these parts still can meet the mechanical property being formed with drill string and unify to add needed for pressure shell, meet the ductility of drilling pipe 42 and the requirement (requiring according to API) of hot strength simultaneously.The rating of machine of valve seat 14 not demand fulfillment drilling pipe 42, therefore these parts can be made up of the different materials being more suitable for the condition that it exposes.This allow to utilize there is inferior mechanical characteristic (such as ductility) compared with high strength steel discussed above but enough anticorrosive to eliminate expensive and valve seat 14 made by the material of chemical treatment consuming time or coating procedure.Valve seat 14 can be made up of such as stainless steel.
If expected, the technique being called as gaseous ion nitriding can be adopted to come to the metal carrying utilized in valve seat 14 for the hardness increased.Glow discharge nitriding is the industrial surface cure process for metal material, and relates to nitrogen-rich gas is contacted with by the workpiece heated, and at this workpiece place, this nitrogen-rich gas is separated into nitrogen and hydrogen.Then nitrogen be diffused on material surface and form nitriding layer, and can select the thickness of obtained nitriding layer and phase composition and the process optimized for concrete property needed for this material.
Tend to region in the environment peeled off by corrosion protective coating adopt stainless steel grade material to be favourable concerning the general corrosion resistance of proposed invention and reliability for all sealing areas are particularly in high speed pressure fluid.Disclose in operating at the scene, assuming that use the material and coating with current design, then between operation, the valve be retained in joint/drilling pipe corrodes very fast.Thus, coated valve member is replaced by the stainless ability of specific class greatly to alleviate or eliminate this problem.
But should be realized that, the condition that valve seat 14 stands means that the deterioration of this part just can not be eliminated simply by selecting the corrosion-resistant material of such as stainless steel and so in practice.In fact, in fact the inferior mechanical characteristic of the material of valve seat 14 selection may cause erosion ratio to increase.But the ability of the valve seat 14 that relatively easy and quick-replaceable weares and teares has relaxed the erosion ratio of this potential increase.
The contact angle of the metal/metal sealing surface between the valve seat 16 on the dish 20b of careful selector valve component 20 and valve seat 14 can reduce the wear rate on the flow region that is included in valve seat 14 further.This angle can be optimized by Fluid Computation dynamic modeling.Optimizing the object of angle is allow fluid to flow through the space between valve seat 16 and dish 20b with more direct mode, because the amount of turbulence when pressure fluid being decreased through the hole of valve chest flows by this, this will reduce again the spoke 22 of valve module 10 and the erosion with critical seal face.The contact angle of sealing surface still can be not limited to 30 degree to 60 degree.
In addition, erosion degree is reduced by the design optimization of the spoke profile being positioned at the collar flange of valve body inserts.This optimization profile be opposing fluid flow pressure requirement of mechanical strength and for fluid flowing shape optimum between compromise.Advantageously, spoke is provided with the completely circular little excessive fillet above and below and between spoke and the external diameter of flow region.
In yet another embodiment of the present invention, valve member 20 is provided with the secondary seal element be made up of different particularly flexible materials, and this secondary seal element is given provides secondary barrier (except being formed in the metal/metal sealing between dish 20b and valve seat 16) by the flowing of side ports 46.In this embodiment (not shown) of the present invention, machined grooves in the side profile of the dish 20b of valve member 20, to allow the potted component of such as polyurethane seal and so on to insert.Sealing element engages with valve seat 16 when valve member 20 is positioned at fastening position.This groove to be processed on potted component in dish 12b and below all there is enough steel, deform when high velocity fluid flow to prevent valve member 20.Under specified temp and pressure condition, sealing element can increase valve member 20 to be sealed in metal/metal seal around any chip that may exist or on ability.When valve module under low pressure uses, such as, when using in gas service, elastomeric seal member may be particularly advantageous, and in this case, metal/metal seal may be unreliable.When elastomeric seal member forms primary seal, also allow metal/metal seal that larger erosion occurred before bad seals, or may mean and no longer need arduously metal/metal seal to be overlapped into the right of coupling.
In addition, advantageously become to have enough degree of depth by groove design, thus make the deformation resistance of dish 20 will prevent potted component from becoming to leave original position, this will eliminate its effect as sealing barrier during pressure fluid flowing.
Additional embodiments of the present invention can be extended to the application comprised in any valve constitution that any replaceable metal insert that is designed to the Fast Wearing adapting to sealing surface and structural element uses in side ports continuous circulation system.This replaceable inserts allows the wear structure only changed in valve, continues to dispose the anticorrosion valve body structure that still can totally play a role simultaneously.This replaceable inserts can also be made up of the material (such as, silicon nitride) different from the remainder of valve module.
